Butterduck?…..I think I go with Tom on this. If by some slight chance your able…maybe you should contact Bill Watterson for advice on an exit plan here.
And, what a bunch of suck-ups in here, kind of embarassing.

So I googled “butterduck”, and there is a Butterduck Farms in Georgia, a man with the last name of Butterduck, and a man in England who had a squash grow like a duck, calling it a Butterduck squash http://www.thesun.co.uk/sol/homepage/news/2737266/Butter-duck-squash.html
I would imagine throwing pepper on the squash would make it tasty, and throwing it on the man would make him sneeze. But the saying made me laugh, and that is all that matters. Please, KEEP your day job.

I had a similar experience with an acquaintance of mine in a hospital ER. We were drunk (it was college) and we were there for another of our friends who fell and broke something (I cannot recall what). So friend was sitting in the waiting chair mumbling incoherently to himself. Those of us still awake were just in the process exchanging knowing glances when something intelligible came out: “I am loopy on ski wax fruitcake.”

Tonight I will wash my hair with butter duck shampoo, eat some butter duck squash, and wash it down with a glass of butter duck wine — served with a dash of pepper (the squash; not the wine or shampoo)

My younger brother actually uses the phrase all the time. He was wearing a duck bill and butterfly wings and running around the house “IM THE MIGHTY BUTTERDUCK” So sorry but I would like to own a small portion of your phrase if it ever happens to be copyrighted.
